An Ipsos study carried out for the Obs’COP reveals that 49% of households limit heating and air conditioning to reduce CO2 emissions but also the amount of their bill. Other very simple gestures help to effectively limit expenses.
1. Reduce the temperature by 1°C
According to ADEME, the simple fact of lowering the temperature of your home by 1°C in winter can reduce your energy bill by 7% per year. In addition, programming a temperature of 17°C at night or even during the day in unused rooms generates even more savings without sacrificing comfort. The right move is to install a connected thermostat to regulate the temperature room by room. This equipment represents 25 to 30% savings on its bill.
In addition, it is advisable to replace your old electric radiators with 3rd generation radiators, which are much more efficient, or to change your heating system. Heat pumps are, for example, an excellent alternative to electric, gas, or oil heating. They can generate savings of up to 80% depending on the technology chosen, as long as they use renewable energies. Admittedly, their purchase and installation have a cost (of 12,000$ on average). But they are eligible for state aid to reduce its bill.
2. Insulate your windows
Good insulation prevents heat loss and therefore energy overconsumption. It is therefore important to reduce drafts in the room as much as possible either by adding seals to the windows or by replacing single glazing with double or triple glazing. Window insulation reduces heat loss by 10 to 15%. Partial removal of the windows will be less expensive than a complete change, frames included. However, this work is eligible for various bonuses (CEE bonus, MaPrimeRénov’, reduced-rate VAT).
The remainder can be financed by financial loans, in particular the eco-PTZ (zero-rate work loan). The amount granted for a single energy renovation action is $7,000 reimbursable for up to 15 to 20 years.
Adding rugs to the floor and thick curtains to the windows, and closing the shutters at nightfall also bring a lot of comfort in winter while maintaining a good temperature in the living rooms.
3. Invest in LED bulbs
LED bulbs are a significant source of savings, with up to 80% less electricity compared to a halogen bulb. And did you know: dusting the bulbs generates between 10 and 15% additional savings. Economical, and energy efficient (their efficiency is 6.8 times higher than conventional bulbs), they are certainly more expensive but they last between 10,000 and 50,000 hours at the rate of 4 hours of daily use.
4. Choose well-labeled appliances
The energy label affixed to appliances informs the consumer about their energy performance. It is advisable to opt for the A+++ label. It is also preferable to maintain them well and in particular to regularly defrost your refrigerator and freezer. According to ADEME, 0.5 cm of ice increases the consumption of the device by 30%.
Eco programs are to be preferred as well as low temperatures and air-drying the laundry. A clothes dryer consumes 200 kWh per year.
5. Turn off sleeping devices
Standby electrical equipment is expensive. By turning them off purely and simply at night, it is possible to save up to 10% of electricity on your annual bill.
